如何将承诺值从一个文件传递到另一个文件？

我的情况很糟糕。我使用 express 和 axios，我想传递 promise 的值，但他们就是不能。有一个服务器文件、身份验证和购物篮。我在服务器文件中获取访问令牌变量，并且必须将其传递给购物车函数。当所有东西都写在一个文件中时，没有问题，当我用单独的身份验证文件编写时，也没有问题，但是当我写另一个单独的篮子文件时，就什么也没有了。

正文文件服务器

const path = require('path');
const express = require('express');           // For web server
const Axios = require('axios');               // A Promised base http client
const bodyParser = require('body-parser');    // Receive JSON format
const querystring = require('querystring');

let app = express();
app.use(bodyParser.json())

app.use(express.static(path.join(__dirname, 'public')));

const config = require('./config');

const PORT = config.credentials.PORT; // import from bim start.js
var FORGE_CLIENT_ID = 'ZqbXzFL8NMXtovqJrLG0O9f5Ar3nQRoE';
var FORGE_CLIENT_SECRET = 'PM4vPHZGQArq99qn';
const scopes = 'data:read data:write data:create bucket:create bucket:read';

app.use((err, req, res, next) => {
  console.error(err);
  res.status(err.statusCode).json(err);
})

认证文件

const path = require('path');
const express = require('express');
const Axios = require('axios');
const bodyParser = require('body-parser');
const querystring = require('querystring');        

const config = require('../config');

var FORGE_CLIENT_ID = 'ZqbXzFL8NMXtovqJrLG0O9f5Ar3nQRoE';
var FORGE_CLIENT_SECRET = 'PM4vPHZGQArq99qn';
const scopes = 'data:read data:write data:create bucket:create bucket:read';

let router = express.Router();
router.use(bodyParser.json());

module.exports = oauth => {
  return Axios({
      method: 'POST',
      url: 'https://developer.api.autodesk.com/authentication/v1/authenticate',
      headers: {
        'content-type': 'application/x-www-form-urlencoded',
      },
      data: querystring.stringify({
        client_id: FORGE_CLIENT_ID,
        client_secret: FORGE_CLIENT_SECRET,
        grant_type: 'client_credentials',
        scope: scopes
      })
    })
  }

在服务器文件中继续验证

let access_token = '';
var oauth = require('./routes/oauth')
app.get('/api/forge/oauth', function(req, res) {
  oauth()
  .then(function (response) {
      // Success
      // let's save token into the varible access_token
      access_token = response.data.access_token;
      console.log(response);
      console.log(access_token);
      // Then, the app is routed to, which creates a shared bucket for our app.
      res.redirect('/api/forge/datamanagement/bucket/create');
  })
    .catch(function (error) {
      // Failed
      console.error(error);
      res.send('Failed to authenticate');
    });
  });

篮子文件

const path = require('path');
const express = require('express');
const Axios = require('axios');
const bodyParser = require('body-parser');
const querystring = require('querystring');        

const config = require('../config');

const bucketKey = config.credentials.client_id.toLowerCase() + '_my_first_full_viewer_bucket';
const policyKey = 'transient'; // Expires in 24hr


module.exports = bucketCreate => {
  return Axios({
    method: 'POST',
    url: 'https://developer.api.autodesk.com/oss/v2/buckets',
    headers: {
      'content-type': 'application/json',
      Authorization: 'Bearer ' + access_token
    },
    data: JSON.stringify({
      'bucketKey': bucketKey,
      'policyKey': policyKey
    })
  })
}

服务器文件中篮子部分的延续

var bucketCreate = require('./routes/bucketCreate')
app.get('/api/forge/datamanagement/bucket/create', function (req, res) {
bucketCreate()
    .then(function (response) {
      // Success
      console.log(response);
      res.redirect('/api/forge/datamanagement/bucket/detail');
    })
    .catch(function (error) {
      if (error.response && error.response.status == 409) {
        console.log('Bucket already exists, skip creation.');
        res.redirect('/api/forge/datamanagement/bucket/detail');
      }
      // Failed
      console.log(error);
      res.send('Failed to create a new bucket');
    });
});

我无法将服务器文件中的 access_token 值传递到购物篮文件，在那里将进行进一步的操作。我也无法将此变量传递给身份验证文件，所以我四处走动，在服务器文件中获取了部分身份验证文件，并使用服务器文件中的 access_token 执行了操作。错误代码 401（如果我没记错的话，还是 403）。无论如何，我将感谢您的帮助。
